摘要： A printhead has a plurality of printing elements and a drive circuit for driving the printing elements aligned in a predetermined direction on an element board. The printhead is provided with a Schmitt trigger having hysteresis properties that give different threshold values to the rising and falling edges of a waveform of a logic signal (HE, LT, CLK, DATA) input into the drive circuit. The Schmitt trigger is provided with means for adjusting the length of the delay at the rising and falling edges of the input waveform signal, so that the speed of data transmission to the printhead can be increased even as the supply voltage is lowered.

摘要： In a printhead in which a plurality of printing elements arranged in a predetermined direction and a driving circuit for driving the printing elements are formed on a single substrate, the printing elements are classified into a plurality of groups. A selection circuit for selecting a printing element to be driven in each group, and data supply circuits for supplying driving data to the driving circuit for driving each printing element through any of a plurality of paths are arranged on the substrate.
